3 | 1. Read the security note below. |
4 | |
5 | 2. Standard GNU package build process: |
95ecb688 |
6 | $ ./configure |
7 | $ make |
8 | # make install |
9 | |
10 | Unfortunately, since this is a beta, there is no good documentation |
11 | yet. For now, use the comments in the public header file adns.h. |
12 | |
13 | |
14 | You will find that adns requires a reasonably standard and up to date |
15 | system. |

17 | The following platforms have been tested at at least some point and |
18 | should work - please report if they don't: |
19 | [adns] OS |
8e26a971 |
20 | 1.0 Linux glibc 2.1 (actually tested on Debian 2.2). |
21 | 1.0 FreeBSD 3.2 |
22 | 1.0 Solaris 2.6, 2.7, 2.8 |
23 | 1.0 HP-UX 10.20, 11.00 |
24 | 1.0 IRIX 6.5 *not* with GCC [1], --disable-dynamic, [2] |
25 | 1.0 AIX 4.1.5, --disable-dynamic |
e32d0f9e |
26 | Later versions of the same OS should work too. [adns] is the latest |
27 | version of adns that has been tested. Usually entries in this table |
28 | mean they pass adns's own regression test, when compiled with GCC. |
29 | Notes/known problems: |
30 | [1] IRIX 6.5 inet_ntoa seems to break with GCC. |
8e26a971 |
31 | [2] Many spurious warnings from this platform's native compiler. |
e32d0f9e |
32 | |
33 | The following platforms are known to be deficient and will not work: |
f9476535 |
34 | Solaris 2.5 Lacks vsnprintf - install glibc ? |
35 | TruUnix64 (DEC UNIX 4.0f) Lacks vsnprintf - install glibc ? |
e32d0f9e |
36 | Please don't report these problems unless you have a nice, |
37 | straightforward solution or workaround for them. |
38 | |

39 | In particular, the build system assumes that you have ELF shared |
40 | libraries. If you don't then please don't send me patches to support |
41 | your kind of shared libraries, and don't send me patches to use |
a5893daf |
42 | libtool. I'm not interested in supporting non-ELF shared libraries, |
43 | and I dislike libtool. If you do not have ELF shared libraries then |
44 | please use the --disable-shared configure option. |

46 | The adnsresfilter utility uses `tsearch' from the C library (a la SVID |
47 | and X/Open). If your C library doesn't have tsearch you will find |
48 | that configure arranges for adnsresfilter not to be built. To rectify |
49 | this, install a C library containing tsearch, such as the GNU C |
50 | library. It is best if tsearch uses an automatically-balancing tree |
51 | algorithm, like the glibc version does. Simple binary trees may |
52 | perform badly. |

54 | You will probably find that GNU Make is required. |

57 | SECURITY AND PERFORMANCE - AN IMPORTANT NOTE |
58 | |
59 | adns is not a full-service resolver. It does no caching of responses |
60 | at all, and has no defence against bad nameservers or fake packets |
61 | which appear to come from your real nameservers. It relies on the |
62 | full-service resolvers listed in resolv.conf to handle these tasks. |
63 | |
64 | For secure and reasonable operation you MUST run a full-service |
65 | nameserver on the same system as your adns applications, or on the |
66 | same local, fully trusted network. You MUST only list such |
67 | nameservers in the adns configuration (eg resolv.conf). |
68 | |
69 | You MUST use a firewall or other means to block packets which appear |
70 | to come from these nameservers, but which were actually sent by other, |
71 | untrusted, entities. |
72 | |
73 | Furthermore, adns is not DNSSEC-aware in this version; it doesn't |
74 | understand even how to ask a DNSSEC-aware nameserver to perform the |
75 | DNSSEC cryptographic signature checking. |
